MACHINE FOR EFFECTING SLOTS IN CARDS FOR STATISTIG OR SIMILAR PURPOSES.

Application filed July 16, 1919.

To all whom it may concern:

. Be it known that I, KARL Earn, LEONARD LTEDSTRAXD, a subject of theKing of Sweden, residing at 9 Volmar Yxkullsgatan, Stockholm, in theKingdom of Sweden, have invented certain new and useful Improvements inMachines for Effeeting Slots in cards for Statistic or Similar Purposes,of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to a. machine for effecting slots in cards forstatistic or similar purposes, for instance slots of the type stated inthe U. S. Letters Patent Nos. 1,261.413, 1,334,957, and U. S.application, Serial No. 311,389, and is described in the followingspecification adapted for effecting such slots in the cards as are shownin Fig. 1 of the Letters Patent No. 1,334,957.

Fig. 1 in the accompanying drawings shows in a plan view and as anexample a machine arranged in accordance with this invention. Fig. 2 isa section on the line 22 of Fig. 1. Fig. 3 is a section on the line 3 3of Fig. 1; the carriage together with the dies being omitted. Figs. 4and 5 show in a side view and a plan view respectively a carriagesupporting the card. Figs. 6 and 7 show in a side View and a plan viewrespectively a movable die together with the matrix and means for movingthe same. Figs. S and 9 show in a side view and a plan view respectivelya further modification of the die and the matrix.

The machine has a carriage l-consisting of a frame and movable onrollers 2, journalled in the frame work 3 of the machine. A frame 5 ispivoted at 4 to the said carriage and between the said frame and thecarriage the card is mount'ed,.in which slots are tobe provided. Theframe 5 is held in its dropped position by two catches 7, movable on thecarriage and acted upon by springs 6 respectively. As the said catchesare disengaged, which is effected automatically in the manner statedbelow, the frame 5 is swung upward to the position indicated by dot-tedlines in Fig. 4 by springs 8, fixed to the carriage and connected withthe frame 5 in any suitable manner, so that the card may be taken out.The lower side of the bottom part of the carriage is provided with teethmeshing with toothed wheels 9 on a rotatable shaft 11 mounted inbearings 10, Fig. 2. The said shaft is provided with a pinion 12 SerialNo. 311,390.

meshing with a pinion 13 on a shaft 14, which at one of its ends has aclutch member 15, which is conical inside and slidable on the shaft butis caused to rotate with the same by a pin and slot connection 16. The

said member 15 may be shifted by a lever not shown, which tends partlyto normally keep the lever arm in engagement with a notch 21, providedin a rod 22, which is slidably mounted in the frame of the machine andprovided with a handle or button, partly to move the part 15 toward theright, Fig. 2. By moving manually the said rod 22 toward the left theclutch member 15 is brought into engagement with a conical clutch member23 provided on a shaft 24, which by means of gearings 25, 26, 27, 28 29is rotated by a shaft 30, connected for instance with an electrio motor(not shown), so that the said member 23 is rotated continuously whilethe machinev is used. The clutch 15, 23 is normally in disengagedposition.

As the carriage 1 is in the position shown in Fig. 3, the card is,placed on the same and the frame 5 is dropped and locked. For moving thecarriage 1 toward the left, Figs. 1 and 3. and placing the card underthe device of the machine providing the cards with slots, a cord fixedto the carriage may be used, Which cord passes round a roller and isprovided with a weight, or a spiral spring may be used, which actuatesa. shaft, provided with toothed wheels, meshing with the teeth of thecarriage, or any other suitable means may be used. The carriage 1 isheld in the position shown in Fig. 3 by two catches 31, engagingprojections 32 provided on the carriage. The said catches 31 aredisengaged by means of a rod 32, slida'bly mounted in the frame of themachlne and actuated manually. On the rod 32 cam pieces 33 are provided,which, as the rod is moved in one direction, force the catches 31 outofengagement with the carriage. The latter is then moved toward the left,Fig. 3, until two projections 34, provided on the carriage 1, strike asecond carriage 35, sl1dably mounted on the carriagel The saidcarriage35 is provided on its top side with teeth, engaging toothedwheels 36 on a shaft 37 journalled in the frame of the machine. On theshaft 37 an escapenient wheel 38 is fixed, co-operating with a doublepawl 39, 40, swingable on a pin 41. From the said pawl an arm 43extends, which is acted upon by a spring 42 and by a link 44 isconnected with a lever 46 pivoted at 45. A manually actuated key plate49 is fixed to arms 4'? swing able on a shaft 48. One of the said arms47 is connected with the lever 46 by means of a'pin 50, so that, bydepressing the key plate 49 the lever 46 is swung on the pin and shiftsthe pawl 39,40 against the action of the spring- 42. In this manner theescapement wheel 38 is permitted to rotate one step in the directionindicated by the arrow, a'ctuated'by the carriage 1 and the carriage'35. Consequently, each time the lrey plate 49 is depressed, thecarriage 1 will be moved onestep towargd-theleft, Fig; 3 and Fig 1viewed in the direction of the arrow, so that the sections of the cards,which are to be provided with slots, may be brought suoces sively intoposition below'the dies respectively. Instead of the escap ement shownin the drawings any escapement of known or suitable construction may beused. As the card has been provided with the desired slots and thecarriage together "with the card is to be brought back to" its startingposition, the clutch '15, 23 is engaged by pushing the rod 22 inwards.The toothed wheels 9 then at'first move the carriage 1 alone toward theright, until two projections 51' provided on the same strike thecarriage 35 and bring the same with themselves. The said carriages arethen moved simultaneously toward the right. As the carriages reach theposition shown in Fig. 3, a projection on the carriage 1 strikes atwo-armed lever 53, pivoted at 52, which is thus swung and moves thelever arm 17 out of engagement with the notch 21 of the rod 22, so thatthe lever arm 17, acted upon by .its spring disengages the clutch member15 fromthe member 23 and the carriages 1 and 35 are brought toastandstill. Ii'nmediately before therarriages come to a standstill, twospring actuated pawls 52 pivoted to the frame of the machine engageprojections on the catches 7, and disengage the same, so that the frame5 is swung upward'by the springs 8 and the card may be removed. In orderthat the pawl 39, 40, during the return movement of the carriages toth'e starting position, may not prevent the escapem ent wheel fromrotating in a direction "opposite to that indicated by the arrow, thepawl 40 is pivoted to the pawl 39 and is held by a spring '54 against anabutment 55 provided 'on the same. The machine may, evldently, be soarranged, that the carriage 1. may be returned manually (by means of ahand lever or the like) to the position, in

which the card is placed on the'same.

For providing the cards with slots of the type shown in Fig. 1 of theLetters Patent No. 1,334,957,the machine is provided with an apparatusfully described in the said Letters Patent. The dies consist of arms,swingably mounted on shafts 58, 59 respectively fixed to end pieces 60of a carriage 61, which is movable in guides provided in thefram'e ofthe machine. In Fig. 1 only the one set of dies is shown. In the saidend pieces 60 rods 62 are fixed, with which and the dies respectivelysprings 63 are connected, which hold the dies respee tively in raised orinoperative position. The carriage 61 is provided with slots 64, one foreach die, so that the carriage forms the nee-- essary matrixf The saidcarriage may be moved toward the left and toward the right, Fig. 1,viewed in the direction of the arrow for placing the necessary pair ofdies under a hammer described blow, which actuates the dies and causesthe same to cut a pair of slots in the card. For the moving -ofthecarriage 61 teeth 65 areprovided on its lower side, which are engaged bytoothed segments 66, fixed toa shaft 67 journalled in the frame of themachine. To the said shaft a third toothed segment 68 is fixed, meshingwith a toothed segment 69, pivoted at 70. An arm 71, provided with ahandle 72, is jointed to the segment 69. Conse quently by swinging thearm 71 the carriage 61 together with the dies is moved. In the fore partof the frame of the machine notches 73 are provided, into which the arm71 may be placed for fixing the osition of the same. At the said notches'gures are provided, indicating which pair of dies is ltH) located underthe hammer. By moving the carriage 61 any pair of dies may be locatedunder a hammer 7 4, which is fixed to a shaft 7 5, journalled in theframe of the machine and movable longitudinally. The said hammer isnormally held in raised position by a below the eccentric and, after thehammer has operated, automatically return the same to its position atthe side of the e ccentric, the machine is provided with a device, whichnow will be described.

From a shaft 80, journalled in the frame of the machine, two arms 81extend which carry a key plate 82,a.dapted to be operated manually. Asthe said plate 82 is depressed. a lever arm 83 is actuated, which ispivoted at 84. The said lever arm 83 is by means of a link 85 connectedwith a bell crank 87, pivoted at 86 and by a pin and slot jointconnected with a swingable arm 89 pivoted at 88. The said arm 89 isconnected with a washer 91, slidably mounted on the shaft 75. Betweenthe said washer 91 and a flange 92 on the shaft 75 a coil-spring 93 islocated, which as the arm 89 and the washer are shifted by means of thekey plate 82, is compressed to such a degree, that its tension isgreaterthan the tension of a second coilspring. 94, provided on theshaft 75 and bearing against the frame of the machine and a flange 95 onthe shaft 75. The arm 89 is held in shifted position by a catch 97,pivoted at 96, as shown in Figs. 1 and 3. As the tension of the spring93 is increased, the spring moves the shaft 75 toward the left, so thatthe hammer 74 is forced against the right hand side of'the eccentric 77,Fig. 1, and, as the eccentric arrives to its upper position, the shaft75 together with the ham-. mer 74 are moved for a further distance, sothat the hammer is located right under the eccentric. The latterposition of the hammer is fixed by a flange 77 provided on theeccentric. The rotating eccentric forces the hammer against the pair ofdies, which for the present is located under the eccentric so that thesaid dies effect two slots in the card. During the working stroke of thehammer an adjustable screw 98 in screw-threaded engagement with a finger99 on the hammer strikes the rear arm of the catch 97 and forces thecatch out of engagement with arm 89, which results in the tension of thespring 93 being decreased and the spring 94 forcing the shaft 75 and thehammer 74 toward the right, as soon as the eccentric arrives to itsupper position. Consequently, the ham mer is automatically returned tothe position, in which it is out of the path of the eccentric andeffects only one blow at a time. As the arm 71, by means of which thecar riage 61 together withthe dies is shifted, is depressed into thenotches 73 respectively, it actuates the key-plate 82 by means of a pin100 provided'for instance on'the handle 72, so that the tension of thespring 93 is in creased in the manner described above without anyspecial manipulation. The machine may be so arranged, that the arm 71actuates also the keyplate '49 for the shifting of the carriage of thedies. The machine shown in spects without departing from the scope ofthe invention. For instance the card may be stationary and the hammertogether with its actuating mechanism and the carriage supporting thedies may be provided on a second carriage, so that not only the dies maybe located under the hammer asstated above but the dies together, withthe hammerand its actuating mechanism may be shifted with relation tothe card, and the dies, which should operate, may be placed above thesection of the card, in which slots'are'to'be effected. I

In Fig. 2 of the Letters-Patent No. 1,334, 957 slots are shown, theinnerend of which coincide, so that each pair of slots formsa singleslot. In order that the machine may be able to effect slots of the saidtype. in the cards, it may be provided with a single die with acorresponding matrix, in which case a relative movement of the saiddieand the card and longitudinally of the die and thus in respect to animaginary plane in the machine is effected so that the total length ofthe parts of the die located at opposite sides of the said plane in eachposition of the die relatively to the card is unvariable; Preferably,the die and the matrix are movable. longitudinally, as shown in Figs. '6and 7. In the said figures 110 designates the matrix. The said matrix ismovable in a guide 111 and is connected, for instance by means of a wire112 of steel or metal, passing round a guide roller 113, with an arm1.1.5, which is swingable round a pin .114 and corresponds to the arm71, mentioned above. The said arm 115 may be shifted along a. scale 116provided on the frame of the machine. By swinging the arm .15 the matrix110 is moved against the action of aweight 117, adapted to move thematrix in opposite direction. 'An arm 118 is pivoted to the matrix andcarries the die 119. 74 is the hammer actuating the die. The actuatingmechanism of the said hflIIliTlGI may be ar ranged in the same man'neras stated above. By shifting the matrix and the hammer the" slot may beprovided in the desired part of the sections respectively of the card.

Also slots, which extend inward from two parallel lines and the totallength of which is unvariable may be effected by means of a by springs(not shown) single die and a matrix belonging to the same, if the partsare arranged as shown in Figs. .8 and-9. Cards provided with such slotsmay be sorted by sticks or the like threaded through the same and movedto' ward one another. In the said figures the die 120 and the matrix 121are stationary. In the matrix 121 a movable piece 122 is provided, whichdivides the matrix into two parts. The die 120 consistso't a pluralityof laminae (eight in the shown example), which preferably have the samesize and are movable toward and from the matrix insuitable guides (notshown). The said laminae are held in the normal position shown in Fig. 8or the like. Above the die a rod 123 is movably mounted, which extendsalong the die andbesides is movable toward and from the same. 123 maybebrought by the hammer 74 to actuate the die. In the said rod 123. anotch 124Jis provided, which is located right above the piece 122 and issomewhat longer than the laminae respectively. The piece 122 and the rod123 may be moved for instance in the same manner as the matrix 110 andthe die 119 in Figs. 6 and and brought on a line with any one of thelaminm of the die 120. As the rod 123 is forced against the die 120 bythe hammer 74:, one of the laminae is inactive viz. the lamina which islocated right below the notch 124i. Consequently, it

the piece 122 and the rod 123 have the position shown in Fig. 8, twoslots are effected in the card, as the hammer 74- is lowered. The lengthof one of the said slots corresponds to the length of the lamina, whilethe length of the other slot corresponds to the total length of sixlaminae. If thepiece 122 and the rod 123are moved into another position,

slots are provided having another length- In each case, however, thetotal length of the slotsis unvariable. Instead of the rod 128 and thepiece 122 being movable, they may be-sta-tionary in which case the dieand the matrix together with-the card are movable.

It will be understood that various changes may be resorted to in theform, construction and arrangement of the several parts withoutdeparting m invention; and hence I do not intend to be limited to thedetails herein shown and described, except as they may be included inthe claims.
